RESUMEN

INTRODUCTION: Patient-report instruments remain the most feasible and sustainable approaches for monitoring medication adherence in clinical settings. However, questions of their reliability and validity persist. Studies suggest that the 3-item instrument for retrospective adherence (IRA) developed by Wilson et al. offers a viable option for clinically monitoring medication adherence. Here we report the reliability and validity of the IRA among patients recruited from community-based HIV clinics and antiretroviral therapy (ART) dispensaries in a resource constrained township in Cape Town, South Africa. METHODS: Women (n = 794) and men (n = 228) receiving ART completed the IRA at three time points: (a) in a face-to-face administration at enrollment (b) in1-week phone interview and (c) 1-month phone interview. Participants also provided contemporaneous blood samples for HIV viral load testing as a clinical outcome and unannounced phone-based pill counts as an objective assessment of ART adherence. RESULTS: The IRA was internally consistent and showed evidence of time stability. The IRA also demonstrated validity with respect to pill count adherence, correlates of adherence, and HIV viral load. Response operating curve analysis yielded an area under the curve of 0.646, using 75% adherence as the cut-off, with 0.637 sensitivity and 0.567 specificity. CONCLUSIONS: The IRA demonstrated reliability, construct validity and criterion validity in a resource constrained setting, supporting use of the IRA in research and clinical care.

RESUMEN

Food insecurity is an established barrier to antiretroviral therapy (ART) adherence among people living with HIV (LWHIV). While insufficient access to food reliably impedes medication adherence, the link between food insecurity and ART nonadherence has not been fully explained. In addition, depression is reliably associated with both food insecurity and ART nonadherence, but again the link between food insecurity and depression is not understood. A potential explanatory mechanism in the associations among food insecurity, depression and ART nonadherence is the experience of food insecurity stigma (FI-stigma). The current study tested FI-stigma in relation to depression as explanatory mechanisms in the association between food insecurity and ART nonadherence. Men and women (n = 495) LWHIV in the southeastern United States completed confidential surveys that included measures of food insecurity, FI-stigma, depression, and ART adherence. Results from the serial mediation model indicated significant direct effects of food insecurity and depression on ART adherence. In addition, food insecurity was indirectly associated with ART adherence through FI-stigma and depression symptoms. Results suggest that the stigmatization of food insecurity predicts increased depression which in turn predicts ART nonadherence, with both FI-stigma and depression symptoms partially mediating the relationship between food insecurity and ART nonadherence. Interventions aimed to reduce food insecurity should include it's associated stigma to improve treatment adherence among people LWHIV.

RESUMEN

Cross-sectional studies have reported that people living with HIV experienced disruptions to social relationships and healthcare during the first year of the COVID-19 pandemic. Furthermore, individuals with less trust in public health sources of COVID-19 information as well as those who held greater COVID-19 prejudicial attitudes experienced greater healthcare disruptions in the early months of COVID-19. To examine changes in trust and prejudicial attitudes in relation to healthcare disruptions during the first year of COVID-19, we followed a closed cohort of 115 men and 26 women ages 18 to 36 living with HIV over the first year of the COVID-19 pandemic. Findings confirmed that a majority of individuals continued to experience disruptions to their social relationships and healthcare over the course of the first year of COVID-19. In addition, trust in COVID-19 information from the CDC and state health department diminished over the year as did COVID-19 prejudicial attitudes. Regression models showed that lower trust in the CDC and health department and greater prejudicial attitudes toward COVID-19 early in the pandemic predicted greater healthcare disruptions over the year. In addition, greater trust in the CDC and health department early in COVID-19 predicted better antiretroviral therapy adherence later in the year. Results support an urgent need to regain and sustain trust in public health authorities among vulnerable populations.

RESUMEN

Advances in HIV prevention tools have outpaced our ability to ensure equitable access to these tools. Novel approaches to reducing known barriers to accessing HIV prevention, such as stigma and logistical-related factors, are urgently needed. To evaluate the efficacy of a randomized controlled trial with four intervention arms to address barriers to HIV/STI testing uptake (primary outcome) and PrEP use, depression, and HIV test results (secondary outcomes). We tested a 2 × 2 research design: main effect 1-stigma-focused vs. health information evaluation-focused counseling, main effect 2-offering HIV/STI testing appointments in person vs. at home with a counselor via video chat, and the interaction of the main effects. Participants (N = 474) residing in the southeastern USA were screened and enrolled in a longitudinal trial. Intervention efficacy was established using generalized linear modeling with binomial or Poisson distributions. Intervention efficacy demonstrated an increase in HIV/STI testing uptake when testing was made available at home with a counselor via video chat vs. in person (83% vs. 75% uptake, p < .05), and participants were also more likely to test positive for HIV over the course of the study in the at-home condition (14.5% vs. 9.4%, p < .05). Stigma-focused counseling resulted in lower depression scores and greater uptake of PrEP among participants < 30 years of age when compared with health information counseling (15.4% vs. 9.6%, p < .05). In order to prevent further disparities between HIV prevention advances and access to HIV prevention tools, we must prioritize improvements in linking people to care. Novel interventions, such as those proposed here, offer a practical, evidence-based path to addressing long-standing barriers to HIV prevention strategies. Trial registration: NCT03107910.

RESUMEN

This study tested the hypothesis that the co-occurrence of alcohol use and depressive symptoms predicts HIV suppression and antiretroviral therapy (ART) adherence among people living with HIV. Baseline cross-sectional results showed a significant interaction between depressive symptoms and alcohol use in predicting HIV suppression; individuals who drank more alcohol and had higher depressive symptoms demonstrated poorer HIV suppression relative to those who had fewer depressive symptoms. In a one-year longitudinal analysis of ART adherence, alcohol use and depressive symptoms measured in daily text-message assessments demonstrated that neither alcohol use nor depressive symptoms alone predicted ART adherence. However, the intersection of alcohol use on days when experiencing depressive symptoms did significantly predict ART non-adherence, for both moderate and heavy alcohol drinkers. Findings suggest that the co-occurrence of alcohol use and depressive symptoms is a robust predictor of poor HIV treatment outcomes.

RESUMEN

Patient initiated decisions to forgo taking medications (i.e. intentional nonadherence) pose significant challenges to managing chronic health conditions. Identifying factors and their underlying mechanisms that impede medication adherence is essential to designing treatment improvement interventions. This study tested a conceptual model that posits the effects of perceived sensitivity to medicines on adherence can be explained by the experience of side-effects, leading to intentionally nonadherent behaviors. Patients receiving HIV care in the southern United States (N = 209) completed measures of perceived sensitivity to medicines, antiretroviral therapy (ART) side-effects, intentional nonadherence and overall adherence. Patients also provided consent to access their electronic medical records to collect subsequent reports of HIV viral load tests. Results indicated that more than one in four participants were intentionally nonadherent to ART. Mediation modeling showed that perceived sensitivity to medicines was associated with greater experience of ART side-effects and intentional nonadherence, which impacted overall ART adherence and HIV viral load. There were also significant indirect effects of perceived sensitivity to medicines on HIV viral load through side-effects and intentional nonadherence. Patients with increased perceived sensitivity to medicines are at risk for poor treatment outcomes and these negative outcomes are partly explained by experiencing greater side-effects and intentional nonadherence.

RESUMEN

OBJECTIVES: We investigated the effects of an enhanced partner notification (PN) counselling intervention with the offer of provider-assisted referral among people diagnosed with STI in a Cape Town public clinic. METHODS: Participants were adults diagnosed with STI at a community clinic. After the standard STI consultation, participants were randomly allocated in a 1:1:1 ratio to (1) 'HE': 20 min health education; (2) 'RR': 45 min risk reduction skills counselling; or (3) 'ePN': 45 min enhanced partner notification communication skills counselling and the offer of provider-assisted referral. The primary outcome was the incidence of repeat STI diagnoses during the 12 months after recruitment, and the secondary outcome was participants' reports 2 weeks after diagnosis of notifying recent partners. Incidence rate ratios (IRRs) were used to compare the incidence rates between arms using a Poisson regression model. RESULTS: The sample included 1050 participants, 350 per group, diagnosed with STI between June 2014 and August 2017. We reviewed 1048 (99%) participant records, and identified 136 repeat STI diagnoses in the ePN arm, 138 in the RR arm and 141 in the HE arm. There was no difference in the annual incidence of STI diagnosis between the ePN and HE arms (IRR: 1.0; 95% CI 0.7 to 1.3), or between the RR and HE arms (IRR: 0.9; 95% CI 0.7 to 1.2). There was a greater chance of a partner being notified in the ePN condition compared with the HE condition, 64.3% compared with 53.8%, but no difference between the RR and HE arms. CONCLUSIONS: PN counselling and education with provider-assisted services has the potential to change the behaviour of people diagnosed with STIs, increasing the number of partners they notify by more than 10%. However, these changes in behaviour did not lead to a reduction of repeat STI diagnoses. TRIAL REGISTRATION NUMBER: PACTR201606001682364.

RESUMEN

BACKGROUND: Evidence-based interventions are needed to stem sexually transmitted infections (STIs). Clinic-delivered counseling remains an important avenue for effective STI prevention. METHODS: A 3-arm randomized clinical trial compared (a) STI health education control condition, (b) risk reduction counseling, and (c) enhanced partner notification counseling. Men and women (n = 1050) were recruited from an STI clinic in Cape Town, South Africa. After baseline assessments, participants were randomly allocated to receive 1 of the 3 single-session counseling interventions and were followed up for 9 months of behavioral assessments and 12 months of electronic medical records abstraction for STI clinic services. RESULTS: Sexual risk reduction counseling reported greater condom use than did the other 2 conditions during the 3 and 6 months follow-ups. In addition, women receiving risk reduction counseling were significantly less likely to have returned for STI clinic services but did not differ in the number of STI clinic visits over the year. CONCLUSIONS: Brief single-session STI prevention counseling demonstrates significant targeted outcomes. The findings suggest that counseling approaches to both increase condom use and enhance partner notification may offer more robust and sustained outcomes and should be tested in future research.

RESUMEN

BACKGROUND: SARS-CoV-2 infection (COVID-19) is potentially severe for individuals with compromised immune systems, including people living with HIV. Along with the direct health threats of COVID-19, there are disruptions to social relationships and health services resulting from mitigation efforts instituted by public health authorities. This study examined the relationship between trust in the government and trust in COVID-19 health information from the US CDC, state health departments, and social media on the experience of COVID-19 social and health services-related disruptions. METHODS: People living with HIV (N = 459) recruited through social media advertisements and chain referrals completed confidential surveys delivered through an online platform. RESULTS: Participants experienced high-levels of disruptions to social relationships and health services attributable to COVID-19 mitigation efforts. We also observed high-rates of inaccurate information and low-levels of trust in government and sources of COVID-19 information. Greater disruptions to social relationships were predicted by more concern about oneself and others contracting COVID-19, whereas disruptions to health services were predicted by greater concern for oneself contracting COVID-19, greater general medical mistrust, and less trust in information from the CDC. CONCLUSIONS: Findings have implications for the necessity of rebuilding public trust in credible sources of health information and stepping up efforts to counter sources of inaccurate information.

RESUMEN

Stigma impedes HIV treatment in multiple ways, including diminished engagement in care, refusing ART, and concealing ART to evade stigma. This study disentangled the degree to which intentionally not taking ART to evade stigma influences overall non-adherence to ART. Patients receiving ART at a community clinic in Cape Town, South Africa (N = 288) completed confidential surveys of demographic and health characteristics, stigma-avoidance non-adherence, and non-stigma-related predictors of non-adherence. Results found nearly half of participants (48%) had forgone taking their ART in social settings. Hierarchically structured regression models showed that alcohol use, medication concerns, and internalized HIV stigma significantly predicted ART non-adherence, accounting for 9.9% of the variance. Stigma-avoidance non-adherence explained an additional 2.6% of the variance in ART non-adherence. The current findings extend previous research to show that stigma-avoidance independently contributes to ART non-adherence, including over and above depression and alcohol use.

RESUMEN

BACKGROUND: Lower health literacy is associated with poorer health outcomes in people living with HIV (PLWH), but the explanatory mechanisms for these associations are not well understood. Factors such as drug use and life chaos may at least in part account for the relationship between lower health literacy and poor health outcomes. The current study tested the hypothesis that lower health literacy would predict drug use, which in turn would predict life chaos, and that all three factors would be related to poorer heath, defined by higher concentrations of HIV viremia. Methods: Patients receiving HIV care (N = 251) at an HIV clinic in the southeastern United States completed computerized interviews and permission to access their medical records. Process modeling tested direct and indirect effects of all variables in a serial mediation model. Results: The direct effects of lower health literacy and drug use were significantly related to HIV viremia. In addition, the indirect effect of health literacy on HIV viremia through drug use was significant. However, results did not demonstrate any effect, direct or indirect, of life chaos on HIV viremia. Conclusion: Findings from this study bolster previous research demonstrating lower health literacy and drug use as barriers to HIV care, and show that lower health literacy impacts HIV viremia, at least in part, through drug use. Interventions aimed to improve HIV treatment outcomes in lower health literacy populations may be enhanced by integrating evidence-based approaches to reducing drug use.

RESUMEN

The life-saving effects of antiretroviral therapy (ART) in treating HIV infection are compromised by alcohol use. A growing body of research shows that both unintentional (e.g., memory lapses) and intentional (e.g., forgoing ART to avoid mixing with alcohol) contribute to ART non-adherence. Beliefs that it is harmful to mix alcohol with ART (alcohol-ART interactive toxicity beliefs) contribute to intentional non-adherence, but their role in overall adherence is not clear. This study conducted a clinic-based survey with 100 men and 193 women (mean age = 36) to examine the prevalence of alcohol-ART interactive toxicity beliefs and whether they contribute to treatment non-adherence in South Africa. One in three (36%, n = 106) participants reported no current alcohol use and 64% (n = 187) reported current alcohol use. The majority of participants, including current alcohol drinkers, endorsed beliefs that it is harmful to mix ART and alcohol, with 57% who currently drink reporting that they forgo taking ART when they are drinking. Participants reported being warned not to mix alcohol and ART from family, friends, and health care providers. In addition, 62% of participants who do not drink, as well as 36% of those who do drink, tell others not to mix alcohol and ART. Mediation modelling found that alcohol use directly predicts ART adherence, and that this relationship is partially mediated by alcohol-ART interactive toxicity beliefs. Health care providers can play a critical role in disputing interactive toxicity beliefs and encouraging patients to take ART even when they are drinking.

RESUMEN

Alcohol use may have significant negative impacts on individuals' ability to remain adherent to antiretroviral therapy (ART), and may also yield other negative psychosocial, health-related, and behavioral outcomes. In addition, false beliefs about the consequences of mixing alcohol with ART use may cause individuals to avoid taking ART when drinking (alcohol-related ART avoidance). Although research conducted in the U.S. and Europe has reported on alcohol-ART avoidance, the current study presents among the first quantitative evidence of alcohol-related intentional ART nonadherence in South Africa. Patients receiving ART from a community clinic in Cape Town (N = 441) completed anonymous surveys of alcohol use, ART adherence, and alcohol-ART avoidance. Results showed that 292 (66%) participants reported current alcohol use; 25% who use alcohol believed that people who drink should stop taking ART when they are drinking and 24% stop their own ART when drinking. Alcohol-ART avoidance mediated the association between alcohol use and ART adherence. Results were robust when controlling for participant age, gender, current care status, and first- versus second-line ART. We found alcohol-ART avoidance may threaten successful ART in South Africa. Corrective messages that take a harm reduction approach to maximize ART adherence when drinking should be implemented in existing clinical services.

RESUMEN

OBJECTIVES: We aimed to identify individual and sexual partnership characteristics associated with partner notification (PN) among people with STI. We hypothesised that PN would be less likely in more casual sexual partnerships and in partnerships with intimate partner violence (IPV). METHODS: We conducted an observational study among the first 330 patients with STI enrolled in a trial of a behavioural intervention to reduce STI incidence, at a clinic in a poor, Cape Town community. We included 195 index patients (those reporting STI symptoms), and conducted longitudinal analyses using participant-completed questionnaires on the day of diagnosis and 2 weeks later. Using partnership data for five recent sexual partners, we assessed factors associated with reported PN with logistic regressions, adjusting for repeated measurements on the same participant for each partner. RESULTS: The sample included 99 males with 303 partners and 96 females with 158 partners. Males reported perpetrating IPV in 46.2% of partnerships. Females reported being IPV victims in 53.2% of partnerships. Males notified 58.1%, females 75.4% of partners during the 2 weeks following diagnosis. Type of partner was an independent correlate of PN for males and females, with the odds of PN lower in more casual partnerships. For males, reporting physical IPV perpetration in the partnership was an independent correlate of PN. For females, there was no association between IPV victimisation in a partnership and PN. CONCLUSIONS: Efforts to decrease the pool of infectious partners need to have a strong focus on the promotion of PN in casual relationships and one-night stands. IPV was not identified as a barrier to PN. In future, we need to investigate the association between IPV with an objective measure of PN success such as partner testing or treatment, or index patient reinfection.

RESUMEN

OBJECTIVES: Novel interventions to address sexual risk taking and slow rates of STIs are urgently needed, in particular among black men who have sex with men (MSM) in the USA. Serosorting, or limiting condomless sex acts to partners of the same HIV status, is commonly practised among MSM, yet can lead to STI and remains largely unaddressed by public health agencies. METHODS: A two-arm, randomised controlled trial was conducted from 2012 to 2015. This trial assessed the effects of a single-session, sexual partner selection and risk decision intervention (experimental arm) versus a single-session, Centers for Disease Control and Prevention-based, sexual risk reduction intervention (control arm) on psychosocial measures, sexual risk taking and STI. RESULTS: At study follow-ups, multiple beneficial changes were observed on sexual risk beliefs measures (ie, changes in serosorting and condom use beliefs, and HIV risk perceptions) and sexual risk taking among the experimental arm relative to the control arm. Overall main effects, however, of the intervention on STI outcomes on year-long follow-ups were non-significant. There was evidence for short-term effects on STI outcomes, and self-report of multiple STIs and STI symptoms demonstrated positive effects over the follow-up period. CONCLUSIONS: Brief interventions to address sexual risk taking can result in short-term beneficial outcomes and can be incorporated into currently existing infrastructure at healthcare agencies. Additional intervention will be necessary for demonstrating long-term results. TRIAL REGISTRATION NUMBER: NCT02128594.

RESUMEN

Background: HIV disproportionately affects sexual minority men, and developing strategies to reduce transmission risk is a public health priority. Purpose: The goal was to empirically test a newly developed, Information, Motivation, Behavioral skills (IMB) theoretically derived, online HIV sexual risk reduction intervention (called HINTS) among a sample of sexual minority men living with HIV. Methods: Participants were 167 men randomized to either the four-session online HINTS intervention or to a time-matched, online control condition. Participants were assessed at baseline and at 6-month follow-up for demographic, medical and psychosocial factors, and sexual risk behavior. Analyses examined group differences in incidence rates of condomless anal sex (CAS) at follow-up with all male sex partners and by partner serostatus, either seroconcordant or serodiscordant for HIV infection. Results: Men assigned to the HINTS intervention reported decreased CAS with serodiscordant partners, a behavior that confers high risk of HIV transmission, compared to the control group. Men assigned to the HINTS intervention also reported increased CAS with seroconcordant partners, a behavior indicative of serosorting. Although the IMB model did not appear to mediate these intervention effects, some IMB components were associated with behavioral outcomes at 6-month follow-up. Conclusions: A new group-based sexual risk reduction intervention conducted exclusively online was successful in reducing HIV transmission risk behavior in a sample of gay and bisexual men living with HIV. Future work should consider utilizing this intervention with other groups living with HIV, perhaps in combination with biomedical HIV prevention strategies.

RESUMEN

BACKGROUND: This article will review qualitative data from intervention-based counselling sessions to explore barriers to partner notification (PN) for South African men and women who have contracted sexually transmitted infections (STIs). This qualitative study took place in a township where there is high STI and HIV prevalence. In addition to reviewing barriers to PN, the study will also identify participants' perceptions about effective PN strategies that are presented during the intervention. Ultimately, the study will assess the intervention's impact on participants' motivation and skills to notify their partners about their STI status. METHODS: Relying on recorded counselling sessions from an intervention run by a parent study, this sub- study reviewed 30 transcripts from counselling sessions with 15 men and 15 women. The intervention was a 60 min interactive session where STI and HIV education, risk mitigation, and effective PN strategies were discussed. Participants were between 19 and 41 years old (mean age = 28.4) and lived within the catchment area of a South African township. Recordings were chosen based on verbal responsiveness of the participant and were manually coded for analysis. In addition, two programme counsellors were interviewed about their perceptions of the intervention and their experiences with participants to enhance rigour and reduce potential bias. RESULTS: By the conclusion of the intervention session, both male and female participants were motivated to notify their partners face-to-face about their positive STI status. Despite this, misperceptions about the etiology and transmission of STIs, as well as inadequate support from the clinical level and power imbalances amongst men and women emerged as major barriers for the prevention of future STIs. CONCLUSIONS: While the intervention appears to be successful in facilitating partners' intentions to notify, the data shows significant social and structural barriers that will create difficulties for the prevention of future STIs. Participants' persistent concerns about acquiring HIV or their current positive status affect decision-making and therefore, could be a window of opportunity for health-care providers or lay counsellors to discuss STIs in high prevalence areas.

RESUMEN

As people living with HIV experience longer life-expectancies resulting from antiretroviral therapy, comorbid conditions are increasing, particularly metabolic disorders. There is potential for psychosocial factors such as stigma experiences, depression, and alcohol use to complicate both HIV infection and metabolic disorders, including diabetes mellitus and hyperlipidemia. While the impact of these psychosocial factors on HIV infection alone are widely studied, their role in potentially complicating HIV co-morbid metabolic conditions has received little attention. This study examined the association between HIV-related stigma and depression, and the potential role of alcohol use as a mediating factor in a clinical sample of patients with comorbid HIV infection and metabolic conditions. Results demonstrated that HIV stigma is associated with depression and this relationship is in part accounted for by alcohol use. Our results indicate that interventions aiming to improve the health of people living with HIV and co-morbid metabolic disorders should prioritize addressing alcohol use as it is related to sources of stress, such as stigma, and depression.

RESUMEN

HIV infection is now clinically manageable with antiretroviral therapy (ART). However, a significant number of people with HIV do not benefit from ART because of non-adherence. This study examined the use of adherence strategies and barriers to adherence among persons at substantial risk for developing resistant virus (less than 75% adherent). People living with HIV (n = 556) who were less than 95% adherent to ART completed computerized interviews, were screened for active drug use, provided medical records for HIV viral load, and completed unannounced pill counts to monitor ART adherence and an assessment of adherence barriers. Based on pill counts, participants were defined as severely non-adherent (≤75% medications taken) and moderately non-adherent (>75% and <95% adherent). Results showed a broad array of memory devices were used to no avail across non-adherence groups. Individuals who were severely non-adherent were significantly more likely to attribute missing medications due to substance use and structural barriers, including running out of medications, inability to get to pharmacy, and inability to afford medications. Results suggest that interventions focused on memory lapses will be insufficient and should rather concentrate on substance use treatment and providing case management to resolve structural barriers to adherence.

RESUMEN

In the U.S., there has been a rise in overweight and obesity among persons living with HIV (PLWH). The aim of this study was to examine dietary intake and body mass index (BMI) in PLWH in Atlanta Georgia relative to the U.S. POPULATION: Dietary intake among PLWH was compared with recommended standards as well as estimated dietary intake for adults in the U.S. Over 31% of the study participants were overweight [BMI = 25-29.9 kg/m2], and 33.1% obese [BMI ≥ 30 kg/m2]. Results indicated significant dietary differences between participants in our sample and U.S. daily recommendations for adults as well as estimated intakes of the U.S. POPULATION: Both males and females consumed more percentage of energy from fat and less fiber as well as fruit and vegetables servings than what is recommended. Results suggest that overweight and obesity are an additional health burden to PLWH in our sample and that their daily dietary practices are not meeting the U.S. government-recommended nutritional standards.
